WILLIAM G. NIEMANN, OF BURLINGTON, IOWA, ASSIGNDR OF ONE-HALF TO GUSTAVEA. ZAISS, OF BURLINGTON, IOWA.

FRUIT-JAR WRENCH.

Application filed July 14,

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, WILLIAM G. NIEMANN, a citizen of the United States,residing at Burlington, in the county of Des Moines and State of Iowa,have invented certain new and useful Improvements in Fruit Jar Vrenches,of which the following is a specification.

My invention relates to an improvement in fruit jar wrenches, used insealing and removing fruit jar caps, and the object is to provide asimple, inexpensive article composed of few parts, which may be easilyand quickly applied, and will exert the required amount of evenlydistributed pressure to turn the caps.

With these objects in view, my invention consists in two jaws hingedtogether, a lever pivoted to one jaw and adjustably connected with theother, whereby the wrench may be fitted to the cap in such a way thatthe required pressure may be applied.

The invention still further consists in certain novel features ofconstruction and combinations of parts which will be hereinafterdescribed and pointed out in the claims.

In the accompanying drawings :Figure 1 is a plan view, Fig. 2 is a-viewof the handle detached, taken at right angles to Fig. 1, Fig. 3 is afragmentary section through the wrench showing the offsets in the hingedends of the jaws, and Fig. 4 is a cross-section through the preferredform of handle.'

A, represents the handle.

F and H are the jaws, to one of which the handle is pivoted at E. Thejaws are preferably made of sheet steel, approximately semi-circular inform, held together by a rivet Gr, whereby to form a hinge, the jawspreferably being ofi'set as shown in Fig. 3, at the hinged ends, wherebyto bring the body portion thereof approximately in alinement.

The handle A may be made of sheet metal bent into U-shape incross-section if preferred, as shown in Fig. 4, although other approvedforms might be resorted to. It is b1 urcated at the pivoted end as shownin Fig. 2, and provided with the orifices L to 1 receive the rivet E.The handle is also provided with a slot O through which the eyebolt Jextends, one end of the bolt J being pivoted as at I to the jaw H, andthe other end provided with an adjustable nut K which operates in theseat B on the handle, this being turned to fit the wrench to the size ofthe cap to be turned. A shoulder D is formed near the pivoted end' ofthe handle to abut against the end of the jaw F to limit the movement ofthe handle in one direction. The dotted lines in Fig. 1 indicatetheposition the handle takes when the jaws are drawn up tight around thecap. To tighten the cap, the wrench is placed on in such a way that inpulling on the handle, it will take the position indicated by dottedlines in Fig. 1, causing the jaws to close and clamp the cap securelyand uniformly throughout its circumference. If the wrench slips inconsequence of not fitting properly, it is simply necessary to turn theadjusting nut a little to the right to reduce the extension of the jaws,and bring their free ends closer toether to fit the cap. In this way,the jaws may be quickly and easily fitted to any size of cap, and thedevice may be applied or removed with perfect ease, and is mosteffectual in the performance of its function.

It is evident that more or less slight changes might be resorted to inthe form and arrangement of the several parts described withoutdeparting from the spirit and scope of my invention, and hence I do notwish to be limited to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire tosecure by Letters Patent, is

1. As an article of manufacture, a fruit jar wrench comprising two jawshinged together at one end, a handle pivotally connected with the freeend of one jaw, an eyebolt pivotally connected with the free end of theother jaw and passing through a slot in the handle, and a nut on thethreaded end of the eye-bolt for adjusting the length of the latterwhereby to fit the jaws to the cap to be turned.

2. A fruit jar wrench comprising two semieireular jaws hinged together,a handle I end seat whereby to adjust the jaw to the cap bifurcated atone end and pivoted to the free to be turned. 7 1 end of one jaw, saidhandle having a seat In testimony whereof I aflix my signature, thereonand provided with a shoulder stop, in the presence of two witnesses.
